BURNER FOR PURIFYING GAS.

Specification of Letters Patent No. 32,124, dated April 28, 1361.

To all whom it may concern:

Be it known that I, JOHN DANKS, of Troy, in the county of Rensselaer andState of N ew York, have invented a new and useful Improvement inGasBurners; and I do hereby declare that the following is a full, clear,and exact description of the same, ref erence being had to theaccompanying drawing, forming part of this specification, said drawingrepresenting a central section of a burner with my improvement.

My inventioniconsists in furnishing a gas burner with a chamber filledwith hemp or liax saturated with nitric acid, such chamber being soarranged that the gas on its way to the external orifice of the burneris caused to pass through the interstices between the fibers of the hempor flax by which it is prevented blowing through the burner and passingolf unconsumed, and is so purified as to produce a very brilliant light.

A is the burner tip which may be of any known kind.

B is the chamber, made of brass, iron or other metal, of spheroidal,cylindrical or other form, made with a female screw socket a, at itsupper end, for the reception of the tip A, which screws into it, andwith a female screw socket at the bottom similar to that at the bottomof an ordinary burner. To provide for the insertion of the hemp or flaxc, c, within it, the chamber B, is divided at the middle of its heightinto two parts which are screwed together at d, d. The hemp or flax c,c, with which the said chamber is filled is in the fibrous condition towhich it is brought by the breaking and heckling or other processes; andafter having been gathered up and well saturated with nitric acid ispacked into the chamber while still wet with the acid. The hemp or flaxpacking c, c, acts mechanically to break the pressure of the gas whenexcessive and so prevent any blowing through the burner without beingconsumed, and preserve a uniform consumption, and a uniform light. Thenitric acid with which the hemp is saturated acts chemically to purifythe gas.

To avoid any corrosive eects of the acid, the burner may be made of, orlined with porcelain or other anticorrosive substance. But the materialof which the burner is composed forms no part of the present invention.Vhen it becomes necessary to resupply the hemp with acid the burner isto be removed from the gas pipe and the acid poured in through theaperture; or the parts of the chamber may be separated and a freshsupply of hemp also inserted.

I do not claim broadly the furnishing of a gas burner with a chamberfilled with fibrous material; but

That I claim as my invention, and desire to secure by Letters Patent, is

The employment as a filling for a chamber B, applied in combination witha burner substantially as described, of hemp or flax saturated withnitric acid, as herein set forth.

JOHN DANKS.
